Awesome apartment with an impressive view over Bangkok right from your bed! The host has been really nice, very reactive, picked me up in Terminal21 which is very near. The location is unbeatable if you like Center Sukhumvit, Nana area and be near BTS.
Only downside is that the facilities are only accessible by fingerprints, and your fingerprint as a guest is limited to the building access. Airbnb rentals are in general not welcome in a lot of condos, but they can't do anything to you as a guest. But this one has a reception lady which is very pushy to know if you rent through Airbnb or not.
